PLS-II에서 삽입장치의 영향에 따른 빔동력학적 분석

Abstract

PLS-II which is a upgraded storage ring of PLS adapts low-emittance to produce high brightness synchrotron radiation. When 20 insertion devices(ID) are inserted,betatron oscillation and tune are distorted. In this thesis, we find the optimum strength of quadrupole magnet that restores the betatron oscillation and tune into the nominal value. We also find emittance and change of energy spread, and the influence of electron beam when the insertion device is inserted. Also the change in dynamic aperture is represented.
